The present invention refers to folders formed of sheet material and of the type constituted of a series of four aligned panels arranged in foldable relationship and used for advertising 01' various other purposes such as greeting cards,

invitation cards or as informative booklets orthe like.

The present invention provides a novel construction of folders of the type mentioned, wherein four aligned panels of equal width provide eight pages on the surfaces of each of which latter illustrative and/or written or other information is applied and the panels are so arranged that on opening the folder in a manner equivalent to normal turning of the pages of a 13008., six of the surfaces mentioned are presented in numeral sequence and when the final turn is made the first page of the series is again presented, which at once indicates that the seventh and eighth pages are concealed thereby involving manipulation of the folds to effect their disclosure which results in setting up increased interest in the terminal subject matter in the folder.

In order to attain the result mentioned, the inner edge of each end panel of the four aligned panels is connected to a flexible link passing outwardly around one end panel folded down on its adjoining panel then through a slot (which slot extends from one to the other of said edges) and thence to the inner edge of the other end panel, the latter being folded down on its adjoining panel in a direction opposite to the fold down of the opposite end panel of the folder.

The accompanying drawing is appended to assist in more fully describing the series of panel folding steps and link locating steps above defined.

Figs. 1 and 2 are plan views of'opposite sides of a sheet blank, Fig. 2 being drawn after reversing Fig. 1 anti-clockwise.

Fig. 3 shows the longitudinal edge of the blank in Figs. 1 and 2, with the beforementioned connecting link positioned in readiness to be passed round one end panel and Fig. 4 is a similar view with the said link about to be folded round the outer end of said panel.

Fig. 5 is also an edge view showing the end panels being folded as beforementioned against the next adjoining panel.

Fig. 6 is a similar view to Fig. 5 showing the panel folding referred to in said figure, approaching completion and with the link passed through the beforementioned slot, while the similar Fig. 7 shows the folding completed and the link final- 1y anchored to the inner edge of the third panel in line.

Fig. 8 is a plan of the folder in complete book leaf order after folding same from the position shown in Fig. '7 and in the directions indicated in the arrows in the lastmentioned figure.

Fig. 9 is a plan view of the folder after the first opening step is performed from the position. in Fig. 8.

Fig. 10 is a plan view of the folder following the next succeeding opening step from the Fig. 9 position.

Fig. 11 is a plan view of the folder following the next succeeding opening step from the Fig. 10 position and which exposes the fifth and sixth pages of the booklet.

Fig. 12 is an edge view of Fig. 9 with pages 2 and 3 folded backwardly.

Fig. 13 is a plan view showing pages '7 and 8 exposed which is obtained by opening Fig. 12 arrangement in the direction of the arrows shown in said lastmentioned figure.

Referring to Figs. 1 and 2 of the drawing, the sheet blank illustrated consists of a flat rectangular sheet of material divided into four aligned panels a, b, c and d of equal width foldably connected together at adjacent edges as shown by fold lines indicated by dotted lines at x. A rectangular tongue 11 (which forms the flexible link beforementioned and is hereinafter designated the flexible link) is formed in the two centre panels b and c by the cutting of a slot 2 and extends from the inner edge of the first panel a to the inner edge of fourth panel d, the fixed end of said flexible link y being located. at said edge of panel a.

The four panels of the blank are numbered on both sides as indicated in Figs, 1 and 2, the numbers representing the consecutive pages of a folder when the blank is in its finally folded position as hereinafter described.

To fold the blank the flexible link y is swung rearwardly about the fixed end thereof (from the position shown in Figs. 2 and 3) and then passed around page 2 at rear of panel a and folded around the outer end of said panel as shown in Fig. 4.

The panels a. and d are then folded against adjacent panels I) and 0 respectively as shown in Fig. 5, the panel a being folded forwardly and the panel 01 rearwardly so that page 7 of panel a faces page 8 of panel b and page 5 of panel d faces page 6 of panel 0.

The flexible link y is now threaded through slot 2 when the folding of panels a and d is almost completed as shown in Fig. 6, the free end of the flexible link being finally passed around the rear of panel d and anchored, as for example by an adhesive strip w, to the inner edge of panel d to form the linkage between the inner edges of panels a and d. The panels a and c are then folded together in the manner as indicated by the arrows in Fig. '7 so that page 2 of panel a faces page 3 of panel 0 to thereby provide a folder in book leaf form with page 1 at the front as shown in Fig. 8.

On opening the folder in the manner of normally opening a book, pages 2 and 3 are disclosed as shown in Fig. 9 and on turning page .3, page 4 is revealed as shown in Fig. 10. On further turning page 4 as opening a book, pages 5 and 6 are disclosed as shown in Fig. 11. Turning of page 6 returns the folder to the position as shown in Fig. 1, with pages 7 and 8 undisclosed.

In order to disclose pages 7 and 8, the folder is opened at pages 2 and 3 as shown in Fig. 9, these pages are folded backwardly to the position shown in Fig. 12, when the folder is opened in the direction indicated by the arrows in Fig. 12 to reveal pages 7 and 8 as shown in Fig. 13. To conceal pages 7 and 8, the abovedescribed folding movements to reveal these pages are reversed.

The blank may be formed of any suitable material and the flexible link be formed either integrally therewith as shown or alternately may be constituted of a separate anchored flexible member of any suitable material such as a ribbon fabric.

We claim:

1. A folder of the type and for the purpose specified, consisting of four panels of equal width each foldably connected to its adjoining panel, a flexible link connected to the inner edge of each outer panel, and a transverse slot extending across the full width of the inner pair of panels, said link extending from one of said inner edges outwardly across one end panel folded inwardly down on its adjoining panel and thence through said slot then across the face of the other end panel folded outwardly down on its adjoining panel and finally to the other of said inner edges.

2. A folder of the type and for the purpose specified, consisting of four panels of equal width each foldably connected to its adjoining panel, a flexible link constituted of a transverse strip cut from and extending the full width of the inner pair of panels, the ends of said flexible link connected to the inner edge of each outer panel and extending from one of said inner edges outwardly across one end panel folded inwardly down on its adjoining panel and thence through the slot formed by the cutting of said trans verse strip then across the face of the other end panel folded outwardly on its adjoining panel and finally to the other of said inner edges.
